Hi, completely new to video editing. Just looking around at different basic editing software right now. One effect I'd like to have in any program I decide on is something I don't even know the name of. It's when a still photo starts from full screen (or even beyond full screen) then gets smaller and smaller as it recedes into the distance, ultimately vanishing. But before it vanishes, another photo appears full screen in the foreground and starts receding, and gets smaller and smaller, and so on and so on, etc., creating a cascading effect. I would like the speed of this receding effect to be adjustable. I hope this description makes sense. Does anyone know what this effect is called?
